Background

Description

Daniel Bleichenbacher discovered that it might be possible to forge
signatures signed by RSA keys with the exponent of 3. This affects a
number of RSA signature implementations, including Mozilla's NSS.

Impact

Since several Certificate Authorities (CAs) are using an exponent of 3
it might be possible for an attacker to create a key with a false CA
signature. This impacts any software using the NSS library, like the
Mozilla products Firefox, Thunderbird and Seamonkey.
